gapping the spark plugs
I've changed my plugs on my 13 3.5 EB twice in 110k. The box that the SP 534 plugs come in say not to change the gap. I gapped them the first time to .28-.30 and it wasn't easy. The second time I left them at the .35 that they come in but get misfires on start up. Whats a good method to gap them. The last change they were well above .30 and no carbon tracking so that's not the issue.

Sounds like you'd want something like this: https://www.maperformance.com/produc...mm-ts-tl-gap12

No problem. I'm curious how that works for you. I just have the old-fashioned thing that grabs the ground so you can bend it. I'll probably get one of these too.
